lineindent.kak
==============
This script provides a way to indent a selection in relation with a
remote line, be it using a relative index or an absolute line number.
Commands

lineindent
~~~~~~~~~~
A single argument is expected by the `lineindent` function, which can
take one of the following forms:
- an integer, which indicates the number of the reference line, e.g. `3`
- a plus sign `+` followed by an integer, which points to a specific
line beneath the current selection, e.g. `+2`
- a negative integer, which points to a specific line above the current
selection, e.g. `-2`
Once the modifier has been passed, it will be used to pinpoint the
reference line, and all the lines within the current selection will be
aligned with it.
Example: indenting lines in a list (the last two lines are selected)
-----------------------------------------------------------------------
- this is the first item of a list
this line was manually indented to match the first item's indentation
this line was typed after that and is part of the current selection
and so is this one
:lineindent -1
